A colleague implemented cascaded SRDF for a VMAX technology refresh and site relocation
activity.
The colleague reports they shutdown the hosts at production Site A and copied all data to the
bunker Site B VMAX. But they are unable to enable SRDF/S between Site B and remote Site C.
What should you advise them?

Refer to the exhibit.

A customer has a legacy DMX-3 at Site 1, where a BCV-R1 copy is taken of the production
volumes and then replicated to another DMX-3 at Site 2 via SRDF/A. The customer will replace
the legacy DMX-3 arrays at both sites with new VMAX arrays.
The customer wants to enable concurrent SRDF on the Site 1 SRDF source volumes, to maintain
disaster restart protection between the legacy DMX-3 arrays and migrate the legacy DMX-3 at Site
1 to the new VMAX array. What should you advise the customer?
